Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Normally, a newborn's immunoglobulins come from the mother during pregnancy and wane after birth until 3–6 months of age, when the infant begins to start to produce their own IgG. However, in transient hypogammaglobulinemia of infancy, the IgG synthesis is delayed, and the hypogammaglobulinemia is prolonged beyond age 6 months. [12]
Generally, people can be grouped as follows: no immunoglobulin production, immunoglobulin (Ig) M production only, or both normal IgM and IgG production. [23] Additionally, B cell numbers are also highly variable. 12% of people have no detectable B cells, 12% have reduced B cells, and 54% are within the normal range. [22]
This shows the levels of albumin and the different immunoglobulins. The serum protein electrophoresis test measures the number of proteins in the serum part of a blood sample. The normal ranges to check for the serum globulin would be about 2.0 to 3.5 grams per deciliter then for the immunoglobulins A, M, and G have different ranges.
IgG 3 deficiency is not usually encountered without other concomitant immunoglobulin deficiencies, and IgG 4 deficiency is very common but usually asymptomatic. [ 3 ] IgG1 is present in the bloodstream at a percentage of about 60-70%, IgG2-20-30%, IgG3 about 5-8 %, and IgG4 1-3 %.

People with this deficiency lack immunoglobulin A (IgA), a type of antibody that protects against infections of the mucous membranes lining the mouth, airways, and digestive tract. It is defined as an undetectable serum IgA level in the presence of normal serum levels of IgG and IgM, in persons older than 4 years. It is the most common of the ...
Patients diagnosed with isolated primary immunoglobulin M deficiency frequently exhibit recurrent infections with common microorganisms as well as a higher incidence of autoimmune and allergy disorders. More than 80% of patients with isolated primary immunoglobulin M deficiency have recurrent infections as their presenting symptom.
